In this task, you're given an article and an answer. Your task is to generate the question for the answer based on the given article.

Example Input: Article: Watching a child struggle to breathe during as asthma   attack is frightening for any parent. So it is only natural that most moms and dads will try just about anything, including spending a lot of money -to keep an attack at bay. Trouble is, more than half of parents are trying strategies that simply do not work and wasting hundreds of dollars in the process. According to Dr. Machael Cabana, a pediatrician at the prefix = st1 /UniversityofMichigan's C.S. Mott Children's Hospital, who led the study, one of the most common mistakes was to buy mattress cover to protect against dust mites for a child whose asthma instead was made by plant pollen  . Many of those parents then neglected to do what would have helped a lot more; shut the windows to keep pollen out. Another was using a humidifier for a child who was allergic to dust mites; a humidifier tends to be a place where dust mites like to breed. With those allergies, a dehumidifier works better. Worst of all was the number of smokers with asthmatic children who didn't even try to quit or at least limit themselves to smoking outdoors rather than just moving to another room or the garage. Many smoking parents purchased expensive air filters that have what Cabana called " questionable utility. " Part of the problem, Dr. Caban and his colleagues believe, is that parents are bombarded by television ads that encourage them to buy products such as air and carpet fresheners, ionizers and other remedies that are often expensive but medically unnecessary. And doctors may not always take the time, or have the time, to explain to parents what will and won't work in their child's particular case. For example, allergies are usually a problem for older children with asthma, while kids 5 and younger more frequently have trouble with viral repiratory infections. So make sure you understand what the cause of your child's asthma really is. 
 Answer: Closing the windows to keep pollen out of the house.
Example Output: What can help the children who are asthmatic according to the passage?

Example Input: Article: A window is more than just an opening that you can see through. It can affect the way a building looks,how much energy a building USES and even how you feel.     Scientists are now working on ncw technologies to create"smart windows". Unlike normal windows,high-tech smart windows can change from clear to dark and back again with the touch of a button --or even automatically as the outside light  changes. Smart windows have the power to make the world a cleaner and more comfortable place. Instead of turning on air conditioners ,people could simply  _ the windows in a building's empty rooms. With the rooms less bright,they would stay cool,and people would save energy and money at the same time.     That's why smart windows are so exciting. Says Claes Granqvist. He's a professor of physics at Uppsala University in Sweden. If you think that you don't care much about windows,you should think again,Granqvist says. Most people who live in developed countries spend about 90% of their time inside buildings and cars. You might spend even more time than that indoors during the winter if you live in a cold climate.     Imagine then what it would be like if there were no windows. You'd have no idea what's going on outside. So,the light of the nature is important for improving the way people feel when they stay indoors. The development of smart windows could mean that a lot of air-conditioning systems may no longer be needed. "In the future," Granqvist says "our buildings may look different." 
 Answer: They can change automatically or by pressing a button.
Example Output: About the smart windows.which of the following is NOT true?

Example Input: Article: The European Union on Monday prohibited the use of X-ray body scanners  in European airports, parting ways with the U. S. Transportation Security Administration, which has used hundreds of the scanners as a way to screen millions of airline passengers for explosives hidden under clothing. The European Commission, which enforces common policies of the EU's 27 member countries, adopted the rule "in order not to risk doing harm to citizens' health and safety." As a ProPublica/PBS NewsHour investigation detailed earlier this month, X-ray body scanners use ionizing radiation  ,a form of energy that has been shown to damage DMA and cause cancer. Although the amount of radiation is extremely low, equal to the radiation a person would receive in a few minutes of flying, several research studies have concluded that a small number of cancer cases would result from scanning hundreds of millions of passengers a year. European countries will be allowed to use an alternative body scanner relying on radio frequency waves, which have not been linked to cancer. The U. S. Transportation Security Administration (TSA) has also used hundreds of those machines --known as millimeter-wave scanners --in U. S. airports. But unlike Europe, it has decided to use both types of scanners. The TSA would not comment specifically on the EU 's decision. But in a statement, TSA spokesman Mike McCarthy said, "As one of our many layers of security, TSA uses the most advanced technology available to provide the best opportunity to detect dangerous items, such as explosives. " We strictly test our technology to ensure it meets our high detection and safety standards before it is placed in airports," he continued. "Since January 2010, advanced imaging technology has detected more than 300 dangerous or illegal items on passengers in U. S. airports nationwide." Body scanners have been controversial  in the United States since they were first used in prisons in the late 1990s and then in airports for tests after 9/11. 
 Answer: They won't risk causing cancer.
Example Output:
Which of the following is true about the new body scanners to be used in Europe?.
